[@NunoMarques76]

Hi Thomas. I've seen a bunch of your videos. Probably most of them by now. However I have a question that's nagging me: what's the fastest you have ever printed with GOOD results? On any stock printer out of all you have tested. And the same question, but for stock printers. I know some people get insane speeds with heavily modded or pro printers, or with "acceptable quality". But I was really curious as to good quality results.

[@jonathanquiceno4777]

Nice I was just about to ask for the settings 👌

Look at the speed view in your Slicer, 150mm/s without a Volcano is not possible, because the volumetric flow rate limits the maximum print speed.

I love how were moving backwards to early printing nozzles. Drilling out the nozzle from an acorn cap nut was the only way to get one back in the day

[@Spitfire17139]

That LTT reference is legendary ! :D Also I think it would have been interesting to talk more about E3D V6 flow limitations. With my usual settings for a 0.6mm nozzle, 210°C, 0.3mm layer height and 0.7mm line width, you are limited to around 60-70mm/s. From my experience that's the sweet spot for a "fast but reasonnable" profile. With a Volcano hotend, you sould be able to easily double that speed but you may be limited by other factors then, mainly cooling as shown in the video but also motion system for cheaper cartesian-prusa style printers, or even extruder if not dual-drive.

[@4991Ares]

If you calculate your flowrate it comes out to something like 12mm3/s, which is about what the regular V6 can handle. E3D doesn't recommend you go over 25mm3/s on a V6 Volcano, but I've taken one to 40. Don't do that.

[@ChristophPech]

To avoid the cooling issues you can use PETG instead of PLA.

[@StormBurnX]

I haven't used prusa slicer before but I do love that cura/creality slicer let you set the rates of inner and outer perimeters individually, so I have my external surface go half as fast as the internal walls and infill for example. Prints absolutely FLY and then when it hits that outer layer it slows down and really brings out the finer detail.

[@coaltowking]

Great video. Seeing those speeds makes me even more happy with my railcore. I built it with a volcano, and use a 1.2mm nozzle. I print at 150mm/s and 9000mm/s² acceleration. I printed a bathroom trash can in less than 5 hours!

[@jefbed212]

That sounds amazing. On a V6, I wouldn't go faster than 16mm/s (floor(15/1.2*1.25*0.6)).

I am so glad you came back to do proper technical videos that are correct and true to their nature, very good level . love it

[@diffeebradley]

I use a 0.8 nozzle with a .4 layer at ~30mm/s when I have large, simple parts. Like, 200 to 500 g parts. I've gotten some beautiful results. Depending on the part, sometimes I reduce the layer height to .2. I use a modified Ender 3 with a Trianglelabs E3DV6 with a dual petsfang duct, so quite a lot of cooling potential. Also, I typically use exclusively PETG which has a significantly lower thermal mass than PLA.

[@4991Ares]

How to print faster in four easy steps: -Establish the flowrate limit of your nozzle. 8-10mm3/s is a good starting point for a lot of hotends, if your cooling is up to that. -Establish the print speed your kinematic system is comfortable with. Most systems can print at 45-60 without excessive ghosting. -Divide flowrate by speed to get the square area your need to print at. In this case, 0.16-0.17 mm2. -Pick a nozzle size and layer height accordingly, as small as you need to meet this but as large as you dare to lose resolution on the print. In this case, 0.6mm nozzle and 0.3mm layer height makes sense. You can now print as fast as your printer will allow at the best resolution this point will offer.

[@massacred666]

What's the calculation done in order to understand step 4? I.e./e.g. how does 0.16 translate to 0.6 and 0.3 height?

I have been using a CR-10 with a Prusa MK3S Hotend/Extruder and a 0.6mm nozzle combined with a printing profile from CNC Kitchen (taken from this video: "FASTER 3D printing of face shields") to great effect. I find the 0.6mm nozzle makes for a good compromise between quality and flow rate and makes for some really good yet fast prints. It might be worth checking out. Also, if anyone is searching for cheap (ish) but good quality nozzles, I can recommend Trianglelabs on Aliexpress. PS absolutely glorious reference to LTT

[@rmatveev]

I didn't get the point of using drilled nozzles with sharp edges. For me it is obvious that it will ruin the quality. For me I wouldn't go beyong 0.8 mm nozzle size on V6 hotend: it will not be able to keep the material temperature out of the nozzle consistent enough.

@@thomashenderson3901 the runout doesn't only change the center of the hole, but it wiggles the drill bit while drilling. Thus, you get an uneven diameter and typically a partially much larger and very inconsistent diameter.

Thanks, very interesting. I use a 0.6 mm nozzle on a MK2.5S with a copper nickel heat block that I have polished dental bits. Titanium break and copper/nickel nozzle. Max flow at 20.5 mm/sec. Very nice finish out of it. Also have found that get better prints out of PETG when staying at 240°C and above and MSR value of 10.5mm/sec. Again thanks for the video. Hope to see you again some time after this madness is over.

[@sxty8goats]

A thought. Step Bore Nozzle. The point that the filament hits would be somewhere @ 0.5mm that would then expand out to 1.5mm or so. That would allow for the back pressuer needed to properly melt the filament and the print / build surface would see a 1.5mm extrusion.

[@Fordham0815]

Thanks Tom for the video. Very very interesting results.

[@Laelaps512]

[@neffk]

If you're limited by the power of your hot end, turning the temperature higher won't make any difference, will it? Example: I lived in Wisconsin in a bad apartment. On a cold day, (-20 oF) the furnace couldn't keep up. Roommate turned thermostat to 90 oF, which had no effect. Next day a warm front comes through and we come home from classes to a sauna.

[@EragoEntertainment]

My Geeetech A10 default hotend for some reason can do pretty fast 0.3mm layer height prints with only 200 °C without skipping, even though it's a short one. The Fox model on 45% scale is 1 hour 30 min (slicer says 1 hour 20 min) on my default 0.2 mm settings.

[@spagamoto]

Putting a 0.8mm on my ancient wooden Ultimaker has been a joy for mechanical parts. It can belt out a strong test piece in 2 hours where my Mk3 would take 8+. Once I retrofit a volcano in there it will be even crazier. Ultimaker is a good candidate for raw speed, being a bowden style machine. The moving parts are light since the extruder stepper is fixed in place. Can crank up the accelerations all the way to 11. Plus, in my experience a bigger nozzle is much less susceptible to jamming, so I can throw all my old sketchy filament at it.

[@kazolar]

So test is -- lets try to test with a benchy, ohh -- looks bad -- inadequate cooling, lets try a model that doesn't need such cooling...huh? I've been trying to push higher speed and higher extrusion printing speed boundaries for years, and first things to upgrade are -- the hotend with a longer melting zone, and cooling to cool filament faster as you're laying it down. Also -- as other suggested, a basic volcano nozzle pack has 1.0 and 1.2mm nozzles included, so why not just use that? I'm not sure what this test accomplishes. You waste more time drilling out nozzles than just doing this the right way. Use a super volcano to test really higher speed printing...

[@ameliabuns4058]

with input shaper i can cut up to 40% of my print time. i went from 2.2k accel at 45mm/s outside perimeters on my printer to 6k accel (only conservatives due the shakig etc) at 150 inner and 90mm/s outer perimeters. it's nut. but these also help ofc. these are my "quality" settings. i get zero ghosting/artifacts. my cooling is also strangely enough. tho i print ABS a lot which doesn't need much cooling

[@pjak2000]

For bigger printers like CR10 or anything with build plate 300x300 a 0.8mm nozzle or bigger is just a common sense. Otherwise you will wait ages for big prints.

[@spunkmire2664]

5:51 that one belt idler or gear on printer sure does wiggle on x axis. does that happen at normal speeds?

[@AmaroqStarwind]

When some people try to print really fast, they end up having to deal with severe vibrations. Regarding excess vibrations when printing at high speeds... If my 3D printer has any springs in it, I'd probably try to replace them with inerters (aka j-dampers) to minimize vibrations. I'd also probably use tuned mass dampers and anti-vibration materials for the mounts and whatnot.

[@natalieisagirlnow]

i thought the "foxy" was your nozzle blob model

[@eulachonfish]

I print industrial parts almost daily with a purchased 1mm nozzle, in PETG. Much better surface finish than you are getting by drilling, due to the flat face on the nozzle. Since print speeds have to be fairly low for PETG, the 1mm nozzle and 0.5mm layer pay off - I can print a benchy in 20 minutes before I run out of hotend capacity. Increasing speeds further results in underextrusion, poor adhesion and uneven parts. Looking at a Volcano or a water-cooled hotend so I can cram even more filament through, even though a 2 hour print for my setup would have been a day with the stock nozzle.

[@aaronrobey9354]

Really nice comparison, however I'm a bit disappointed the test wasn't done with a sanded-down nozzle. I would be so curious to see how a flatter nozzle would increase the quality.

[@kzinty]

I did a part with a volcano hit end with 0.6mm that had the 0.2mm layers. The part was incredibly strong. The part was a tesla valve printed on end. Detail needd more refining but I good not break it by hand. It would be a good comparison for part strength purposes

[@knoopx]

FIY, klipper the new 3d printer firmware recently added "resonance compensation" and it's awesome. I cranked up my acceleration/speeds by 3 with mostly no quality loss.

[@peterjigstad9755]

I've printed with a 1.5 mm nozzle with 200% speed using point 0.5 instead of 100% larger nozzle without tuning the temperature cooling in half the speed, knowing that 75% ratio is equal to the original printer's perimeters and showing that 30% infill on all layers gets a 200% speed at stock 0.2 millimeter nozzle and two multipliers which is now not as much of improvment compared to 250 mm speed at max and therefore I've come to the final conclusion that I should keep the standard nozzle, the normal speed and original cooling and wait a bit longer for the real good results. LOL

[@jefbed212]

For 1.5mm nozzle, I'd recommend to set your extrusion width to 1.875mm, layer height to 0.75mm, and all speeds to 10 mm/s.

[@DrewLSsix]

I know this is a few years old, but im thinking about it a few different ways, a 6mm bolt drilled out to the 1.xmm sizes, the head can be finished to provide a nicer surface. Or an 8mm nozzle can be fabricated with a heatblock to match to get back the strength.

[@ShadowRam242]

My endgame plan on my custom build for speed and quality is to have 2 nozzles. 0.4 nozzle for outer perimeter, 0.8 nozzle for infill.

[@lukerickert5203]

Print speed isn't a big deal for me but I find 0,6mm nozzles to work great. They give twice the area (flow) of a 0,4mm but are small enough the parts look about the same for anything functional. You can buy those but if you want something special let me know and I can make nozzles and send you some.

I am running into the thermal runaway protection on my MK3S when I print parts with large flat surfaces using a 0,6mm nozzle. Putting down two or three bottom layers for a 10x15cm box tends to trigger thermal runaway on the second or third layer. Even had it trigger at the top layer before when printing a formula style sim racing wheel. I like larger nozzles for big prints but they come with their own issues. Really sucks when a large print fails after 5 hours where the 0,4mm nozzle could have finished the same job in 8.

[@jeffmilkey]

Failures always suck,,but we are working to get print times down.....that is the goal

[@petrkubena]

If you are going down to 0.4mm layer height, 0.8mm nozzle would be probably better - you get more evenly heated filament with same layers or you could possibly go for 0.6mm layer height and you would still be extruding slightly less material than on 0.4mm layer height with 1mm nozzle. Anyway thanks for the test and the lt tea :)

nice video! LOVE to see the prusa run fast af I actually don't like visible layers (unless it's a vase, those look super cool with thick lines on purpose) I spent a lot of money getting a Nova hotend to push high volumetric flow out of a .5 nozzle at .2 layer heights, it's worth it for me, I prefer needing the printer to run 300mm/s 3k accel print speeds to using thicker layers, compared to a printer running 40mm/s, I get 5x faster print times (although I don't usually go that fast, usually only 150mm/s untill I get the better machine I designed specifically for speed), cooling is definitely the limiting factor most of of the time, that's why I'll be using a 5020 fan instead of the 5015, makes a huge difference

Watching this video quite a while later, I'm curious how far you can take it with the CHT high-flow nozzles. After all, for bigger prints it seems to be the flow rate that causes the most issues. Cant wait to get my hands on my prusa mini with some CHT nozzles and figure out where i can push it to. Edit for clarification: I plan on getting a 0.6 mm nozzle, as it should be able to print line widhts of down to 0.48mm comfortably [if not lower] yet still go for a higher layer height [up to 0,4]mm, not to mention a line width of up to 0,8 comfortably, if the flow of the CHT nozzle suffices. Nope, I am not in this to print detailed intricate models. I want to learn how to 3d Model functional parts, and draft quality is plenty.

[@besenyeim]

IDEA: Two heads, same (or similar) material loaded, different nozzle sizes. Outermost perimeters with small head, high resolution settings, small layer height, etc. Inner walls and infill with large, 2x, 3x, or 4x layer height. So the layers would go like this: multiple thin layers of outer walls with high res., then a thicc one inside. I'm sure I'm not the first to come up with this, but I haven't seen it working yet.

[@smithfamilydesigns2012]

How accurate are the diameters of the drilled nozzles? If your drill bit wobbles, or has a tolerance that's slightly off (say 0.98mm or 1.02mm).. I imagine you can compensate for that in horizontal expansion settings... but is it worth it or easier just to buy the bigger nozzles?

[@andyh8239]

Prusa Slicer - Nozel size - doesn't seem to affect speed or the number of passes to fill an area.

[@laurastanleyneelindquist1806]

Pretty new to 3D printing. How do you develop a tuned profile? I've just played with infill and perimeters and a tiny bit with temperature. Would love to see a how to.

[@TheDarkDude]

Briefly explained, you keep changing factors such as speed and as you find issues you adjust other settings to counter it, such as increasing temperature. I use a 0.8mm nozzle at 0.2mm layers most of the time (I print bigger things, but as long as you don't need too much detail it's good for small pieces too) and getting the flow rate right can take some back and forth with speed and temperature. Then there's issues with stringing and blobs which comes with higher temperatures and bigger nozzles.

Hi, I bought a set of nozzles ranging from 0.2 upto 1.0 I have experimented with the 0.8 but I didn't like the layer's, I prefer using 0.4 although the 0.2 had a very nice finish and took longer, some of the things I print need a little more detail so I have to factor in for the extra time. What I have considered playing with using a bigger nozzle is TPU (for RC tyres or something). Have you ever tried this?

[@jvleugels]

Have you ever tried the pre slices files of Prusa for their face shield? I was shocked how fast they push their settings for that. But with PETG it is easyer to go faster since it does not need as much cooling. I saved their settings to my slicer and use it now for all prototype prints.

Regarding the smell, I find particularly black pla from das filament is very smelly. I almost felt a bit sick from it when I started using it.

So what are the best options for powerful cooling? I've seen some people with fast printers running compressed air, which is good 'cos gas absorbs heat as it expands (in addition to the air flow cooling) but I'd worry about blowing around delicate parts.

No link in the desc to the foxy model?

How about wider line width on stock nozzle? And how about external perimeters around 0.45mm and all internals 0.7 width? This way you could have thicker walls and accurate externals.. On dimensionally accurate prints I prefer 0.1.. 0.2mm layer thickness because thicker ones affects accuracy quite a lot (for example try printing different thickness walls 1mm to 2mm, on thicker ones the walls are not that accurate anymore).. I've been using 0.6mm nozzle from start but now have tested more on 0.4mm printing thicker lines which seems quite efficient -just gotta test 0.4 with carbon if it's OK and not clogging. 👍

Are there any manufacturers of nozzles with dynamic apertures? This seems like a weird idea, but a nozzle which could have its diametre adjusted with extra electronics would permit a single-nozzle system to function as multiple with vtool profiles.

It would be nigh-impossible to make that for a reasonable price. the electronics would have to endure high heat and be tight so that the super hot plastic flowing through them doesn’t seep through or get stuck somewhere. In addition, it would have to be small enough to actually work as a nozzle. Cool Idea but very hard to implement.

I know it's not the point of the video, but you can achieve similar results with a lot less artifacts simply by increasing the line width. I regularly run 0.6mm line width on a 0.4mm nozzle, and have gone as wide as 0.8mm with minimal issues. Higher than that you start running into the limits of the hot end to melt the volume of filament needed, forcing you to print slower which defeats the purpose.

I like the LTT reference. Had to Lough out loud. And now I understand what you meant with your tweet a few days ago. But all that work just for this joke? I might use it and get some tea so you earn a few cents at least 😀

Good info in this video. Thank you

[@bassgojoe]

I use a 0.5 nozzle and 0.3 layer height, it’s the best quality speed tradeoff for the stuff I print.

What about 2 head printer 1 mm for infill and smaller for the outside
